This film documents the Sullivan C. Richardson Pan American Highway Expedition of 1940-1941, the first of a two-part series describing the first successful attempt to drive an automobile from the United States to the tip of South America (the companion film was 'Rugged Road to Cape Horn.')Here, Richardson and two companions (one of whom is Arnold Whitaker) explore the route that would eventually become the Pan American Highway. The going is rugged: at times, their Plymouth sedan is towed by men and burros through difficult terrain. On the way, they visit Mexico City and meet President Miguel Alemán, witness the Mayan site of Monte Albán, Lake Atitlán in Guatelama, and view hat weaving in El Salvador.
